Connective tissue is made up of cells spread out through an extra-cellular matrix. These cells produce the matrix which holds fibers contained in a liquid, jelly, or solid. There are six types of connective tissues: loose connective tissue, fibrous connective tissue, adipose tissue, cartilage, bone, and blood. Cartilage usually forms at the ends of bones and serves as a shock-absorbing substance. It also supports disks in between vertebrae and makes up most of our ears and noses.
